    Hi,

    I have a Mac Pro 1.1 with the following specs

    - 250 Samsung SSD
    - 13GB Memory
    - Radeon R9 270X 2GB card - Cinema Display 27"
    - Nvidia 7300GT OEM card - use this for bootscreen.
    - Windows 7

    I recently installed Windows 7 (I don't have OSX installed at all) and noting my CPU usage is at 90% - 100% all the time, its a new copy of Windows 7, so it can't be a virus?

    Any idea?

    Have you looked to see what process is causing the usage figure to be so high?

    Mixing AMD and Nvidia? 7300GT is long out of date. This is "out of box" or you installed ____ ?

    13GB - get rid of the 2 x 512MB FBDIMM, and you have 64-bit Pro? 32-bit = 1.9GB memory only

    have you downloaded any torrents or touched to the internet in windows if so it may be a virus or something :p

    look at running process and see what is using 90-100% cpu then google the name

    do you have any protection ? Microsoft security essentials is free and what i use
